74LCX14 Low Voltage Hex Inverter with 5V Tolerant Schmitt Trigger Inputs Features General Description 5V tolerant inputs The LCX14 contains six inverter gates each with a Schmitt trigger input. They are capable of transforming slowly changing input signals into sharply defined, jitterfree output signals. In addition, they have a greater noise margin than conventional inverters. 2.3V-3.6V VCC specifications provided 6.5ns tPD max. (VCC = 3.3V), 10A ICC max. Power down high impedance inputs and outputs 24mA output drive (VCC = 3.0V) Implements patented noise/EMI reduction circuitry Latch-up performance exceeds JEDEC 78 conditions ESD performance: - Human body model > 2000V - Machine model > 200V Leadless DQFN package The LCX14 has hysteresis between the positive-going and negative-going input thresholds (typically 1.0V) which is determined internally by transistor ratios and is essentially insensitive to temperature and supply voltage variations. The inputs tolerate voltages up to 7V allowing the interface of 5V, 3V and 2.5V systems. The 74LCX14 is fabricated with advanced CMOS technology to achieve high speed operation while maintaining CMOS low power dissipation.
